Description

A welding device for the outer frame of a denitrification catalyst Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding device for the outer frame of a denitrification catalyst. Background Technology

[0002] As a key supporting component in the flue gas purification system, the welding quality of the outer frame of the denitrification catalyst directly affects the installation accuracy and service life of the catalyst. However, traditional welding equipment often uses a single-layer fixed platform with simple clamps, which is difficult to meet the requirements of high-precision positioning and stable clamping. Especially when welding multi-layer frames, operators need to frequently adjust the workpiece posture to adapt to welds in different positions, which is not only inefficient but also prone to frame deformation, affecting the overall structural stability, and making it impossible to achieve continuous three-dimensional welding operations.

[0003] Furthermore, existing clamping systems generally rely on bolt locking, requiring frequent replacement of positioning modules when dealing with frames of different sizes, leading to increased auxiliary time and severely limiting welding efficiency. Simultaneously, the lack of effective collection measures for harmful fumes generated during welding allows metal vapors and spatter to diffuse in the working environment, posing significant health risks to operators. Although some improved equipment attempts to introduce a rotating worktable structure, these often suffer from problems such as large space occupation and interference between the tilting mechanism and the welding torch's movement path, making it difficult to achieve synchronous and efficient welding of welds on both the inner and outer sides of the frame. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a welding device for the outer frame of a denitrification catalyst.

[0005] A welding device for the outer frame of a denitrification catalyst includes a base, supporting guide rods, a mounting frame, a top mounting shell, a welding machine, a vacuum pump, a welding line, a welding head, sliding fixing rings, and clamping components. Four supporting guide rods are connected circumferentially to the base, and a top mounting shell is connected between the top of the supporting guide rods. The welding machine and the vacuum pump are connected to the top mounting shell. The welding line is connected to the welding machine, and the welding head is connected to the welding line. Sliding fixing rings are slidably connected to each supporting guide rod, and a mounting frame is connected between the sliding fixing rings. At least eight clamping components are evenly spaced circumferentially to the mounting frame.

[0006] Furthermore, it also includes L-shaped support rods, with at least two L-shaped support rods connected to the bottom of the top mounting shell.

[0007] Furthermore, the clamping assembly includes slide rods, guide members, screws, and L-shaped clamping plates. The mounting frame has at least eight slide rods slidably connected at even intervals along the circumference. Each slide rod is rotatably connected to a guide member, each guide member is threadedly connected to a screw, and each screw is rotatably connected to an L-shaped clamping plate.

[0008] Furthermore, the clamping assembly also includes a first nut, and the slide rod has a threaded groove, through which the first nut is threadedly connected.

[0009] Furthermore, the clamping assembly also includes a sliding clamp and a second nut. The second nut is threaded onto the screw, and the sliding clamp is slidably connected to the screw. The second nut is fixedly connected to the sliding clamp.

[0010] Furthermore, both the L-shaped clamp and the sliding clamp are equipped with anti-slip textures.

[0011] The present invention has the following advantages: The present invention is equipped with an air extractor and a clamping assembly. The air extractor removes the harmful gases generated during welding, thereby reducing the concentration of harmful gases in the air and protecting the health of the operators. The clamping assembly flips the frame, which facilitates continuous welding of the welds on the inner and outer surfaces of the frame, avoiding the inconvenience and errors caused by frequent manual adjustment of the workpiece posture and improving welding efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A welding device for the outer frame of a denitrification catalyst, as shown in Figures 1-5, includes a base 1, supporting guide rods 2, a mounting frame 3, a top mounting shell 4, a welding machine 5, a vacuum pump 6, a welding line 7, a welding head 8, an L-shaped frame rod 9, a sliding fixing ring 10, and a clamping assembly. Four supporting guide rods 2 are fixedly connected circumferentially to the base 1. The top mounting shell 4 is fixedly connected between the tops of the supporting guide rods 2. The welding machine 5 and the vacuum pump 6 are fixedly connected to the top mounting shell 4. The welding machine 5 is fixedly connected to... There is a welding line 7, and a welding head 8 is fixedly connected to the welding line 7. At least two L-shaped brackets 9 are fixedly connected to the bottom of the top mounting shell 4. When the welding head 8 is idle, the welding line 7 is wound around the L-shaped bracket 9 for storage. When welding is required, the welding line 7 can be removed from the L-shaped bracket 9. Sliding fixing rings 10 are slidably connected to the support guide rods 2. Mounting frames 3 are fixedly connected between the sliding fixing rings 10. At least eight clamping components are fixedly connected at even intervals along the circumference of the mounting frame 3.

[0020] As shown in Figures 1, 2, 4, and 5, the clamping assembly includes a slide rod 11, a guide member 13, a screw 14, an L-shaped clamping plate 15, a first nut 12, a sliding clamping plate 16, and a second nut 17. The mounting frame 3 is slidably connected to at least eight slide rods 11 at uniform intervals along the circumference. Each slide rod 11 is rotatably connected to a guide member 13, and each guide member 13 is threadedly connected to a screw 14. Each screw 14 is rotatably connected to an L-shaped clamping plate 15. The slide rod 11 has a threaded groove, and the first nut 12 is threadedly connected to the slide rod 11 through the threaded groove. The second nut 17 is threadedly connected to the screw 14, and the sliding clamping plate 16 is slidably connected to the screw 14. The second nut 17 is fixedly connected to the sliding clamping plate 16. Both the L-shaped clamping plate 15 and the sliding clamping plate 16 are provided with anti-slip textures.

[0021] When welding the outer frame of the denitrification catalyst, move the sliding fixing ring 10 to slide it on the support guide rod 2, thereby adjusting the height of the mounting frame 3. Then rotate the screw 14 to move the L-shaped clamp 15 away from the center of the mounting frame 3, placing the frame on the L-shaped clamp 15 so that the L-shaped clamp 15 supports the frame. Then reverse the screw 14 to move the L-shaped clamp 15 closer to the center of the mounting frame 3, so that all eight circumferential L-shaped clamps 15 simultaneously clamp and fix the frame. Then weld the frame, using circumferential multi-point clamping to ensure the overall stability of the frame. When welding the bottom of the frame is required, rotate the screw 14 to loosen the L-shaped clamps 15, clamping the frame edge only through two of the front and rear clamping components. During this process, move the frame edge between the L-shaped clamps 15 and the sliding clamp 16 in one of the front and rear clamping components, and rotate the second nut 1. 7. Move the sliding clamp 16 closer to the L-shaped clamp 15, thereby clamping and fixing the frame edge through the L-shaped clamp 15 and the sliding clamp 16. Rotate the frame to rotate 180 degrees along the axis of the front and rear guide members 13, thereby completing the frame flipping. Then, perform subsequent welding processing on the frame to facilitate continuous welding of the welds on the inner and outer surfaces of the frame, avoiding the inconvenience and errors caused by frequent manual adjustment of the workpiece posture, improving welding efficiency, meeting the welding needs of complex spatial structures, and adapting to the processing requirements of multi-directional welds. After the frame is completely welded, flip the second nut 17 to make the sliding clamp 16 slide away from the frame, and then remove the frame from this welding device. During welding, the exhaust fan 6 removes the harmful gases generated during welding, which can reduce the concentration of harmful gases generated during welding in the air, thereby protecting the health of the operators.
